Improvement in varnishes or bronze coatings for articles of plaster, iron, wood



To all whom it may concern: a V l Be it known that I, CHARLES RoTTER, of East Birmingham, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Varnish, of which the following is a specification: p The object of my invention is to furnisha durable bronze varnish in difl'er'ent colors for coating and protecting plaster of Paris, terra cotta, stucco, wood and iron ornaments, and busts, which may be placed outside, exposed a to the weather, or inside, to be cleaned by the use of Water, as occasion requires. The brilliant hue and the protecting qualities of this a plaster ornaments. My invention consists in the mixture of mica silver and aurosit with collodion, in connection with aniline and other colors to produce difl'erent tints.

By mixing one-half ounce of mica silver (argentine mica) with three ounces of clear collodion, and shaking it thoroughly, a brilliant silver varnishis obtained, which may be' colored to any desired shade or tint by the addition of aniline colors. These aniline varnishes are more suitable for insidepurposes, t as they are too quickly changed by the influ ence of the sun and rain.

By the mixture of half an ounce of aurosit UNITED STATES CHARLES ROTTER, OF EAST BIRMINGHAM, PENhISYLVANIA. "I:
